Decision level

Algorithm

Selection

Set1

All the <area> tags, defined within a <map> tag whose the "id" attribute corresponds to the "usemap" attribute of an <img> tag and not identified as captcha (see Notes about captcha detection)

Process

Test1

For each element of Set1, raise a MessageA

MessageA
  • code : ManualCheckOnElements
  • status: Pre-Qualified
  • parameter : "href" attribute, tag name, snippet
  • present in source : yes

Analysis

Not Applicable

The page has no <area> tag, correctly associated with an image (Set1 is empty)

Pre-qualified

The page has at least one <area> tag, correctly associated with an image (Set1 is not empty)

Notes

An element is identified as a CAPTCHA when the "captcha" occurrence is found :

  • on one attribute of the element
  • or within the text of the element
  • or on one attribute of one parent of the element
  • or within the text of one parent of the element
  • or on one attribute of a sibling of the element
  • or within the text of a sibling of the element
